Troubleshooting
DTC 63: Reference Voltage
Check for a short to body ground
in the VREF circuit:
1. Disconnect the PCM connec-
tor D (22P) and the VSA con-
verter unit 26P connector.
2. Check for continuity between
the PCM connector D (22P)
terminal No. 20 and body
ground.
Is there continuity?
Is there about 5 V?
Check for an open in the VREF
circuit:
Measure the voltage between the
VSA converter unit 26P connec-
tor terminal No. 23 and body
ground.
Is there about 5 V?
The system is OK at this time.
If the problem recurs, replace
the VSA converter unit.
Repair short to body ground in
the wire between the PCM and
the VSA converter unit.
Check for loose terminals in the
PCM connectors. If necessary,
substitute a known-good PCM,
and recheck.
PCM CONNECTOR D (22P)
Wire side of female terminals
VSA CONVERTER UNIT 26P CONNECTOR
Repair open in the wire between
the PCM and the VSA converter
unit.
Wire side of female terminals
Check the PCM:
1. Connect the PCM connector D
(22P).
2. Turn the ignition switch ON
(II).
3. Measure the voltage between
the PCM connector D (22P)
terminal No. 20 and body
ground.

DTC 64: Sensor Power Source
Check for a short to body ground
in the PSU circuit:
1. Disconnect the VSA control
unit 42P connector and the
pressure sensor 3P connector.
2. Check for continuity between
the VSA control unit 42P con-
nector terminal No. 42 and
body ground.
Is there continuity?
Check for a short to body ground
in the YRSA YU circuit:
1. Disconnect the yaw rate/later-
al acceleration sensor 6P con-
nector and the steering angle
sensor 4P connector.
2. Check for continuity between
the VSA control unit 42P con-
nector terminal No. 39 and
body ground.
Is there continuity?
Problem verification:
1. Clear the DTC.
2. Test drive the vehicle at 6 mph
(km/h) or more.
3. Verify the DTC.
Is DTC 64 indicated?
Check for loose terminals in the
VSA control unit 42P connector.
If necessary, substitute a known-
good VSA modulator-control
unit and recheck.
VSA CONTROL UNIT 42P CONNECTOR
Wire side of female terminals
Repair short to body ground in
the wire between the pressure
sensor and the VSA control unit.
Repair short to body ground in
the wire between the yaw
rate/lateral acceleration sensor,
the steering angle sensor and
the VSA control unit.
The system is OK at this time.

Troubleshooting
DTC 65: Brake Fluid Level
Is the level OK?
Refill the brake fluid.
Check the brake fluid level switch.
Is the switch OK?
Replace the brake fluid level
switch.
VSA CONTROL UNIT 42P CONNECTOR
Check for a short to body ground
in the BFL circuit:
1. Disconnect the VSA control
unit 42P connector.
2. Turn the ignition switch ON (II).
3. Measure the voltage between
the VSA control unit 42P con-
nector terminal No. 36 and
body ground.
Is there battery voltage?
Repair short to body ground in
the wire between the gauge
assembly and the VSA control
unit.
Wire side of female terminals
Check for loose terminals in the
VSA control unit 42P connector.
If necessary, substitute a known-
good VSA modulator-control
unit, and recheck.
Check the brake fluid level.
